What is the general limit on the length for extension cable between a controller and a strip light? I'm doing some research and was wondering what the farthest distance might be that I can place a strip from the controller and power supply unit. I figure closer, multiple controllers would fix this issue, but I'm curious if it can be done with a centralized controller. Some information for the potential setup would be: 30led / meter 10 pixel per meter strip and a 16 output aplhapix controller Two 350w 12vpower supplies, one per bank, one strip per output 18 AWG extension cable, pigtails on either end, connected to pigtails coming out of the controller and the strips My absolute farthest strip might be 60ft / 18 meters feet from the controller. The next farthest 55 ft, then 50, 45, 40, 35, 30, 25. These 8 would be on one bank and be located for example to the left of the controller. The other bank would have strips located to the right of the controller, all closer than the closest strip from the other bank. Actual straight line distance is less, like 40 ft for the farthest strip, but these measurements allow for flexibility around obstructions and an easier route to the controller. Ideally I would be able to place the controller right in the middle of the left and right, but the only practical way seems to be a location that puts it closer to the right side strips. Would these or some of these distances require power injection or a null pixel, or both, or anything else? From what I've seen, after 25 feet or 7-8 meters might need at least power injection. Are there any other issues to consider even if this was the case?
